My view is we need a model of the radiation (i.e. the visible light, the "physics" part people refer to) and a model of the sensor. I make some images for people to look at, some images for a simulation of an infrared sensor to look at, and some for the simulation of a camera in a robotics system to look at. Having a sensor model I can determine the accuracy I need in my radiation model, and avoid chasing down every photon. People have used psychophysics a lot, i.e. for color and anti-aliasing, but we need to do more to tie in a model of perception to the radiosity, or monte carlo solution we do for the radiation so we don't have to compute forever to get little variations that no one can see. -- Holly Rushmeier hr3@hydra.gatech.edu
